The Zero Trust model is a security approach that assumes that all network users, devices, and resources are potentially untrusted and that every access request must be verified before being granted. This is in contrast to the traditional security model, which assumes that users and devices within the network can be trusted and that only external threats need to be guarded against.
In a Zero-Trust environment, all access to resources is controlled through the use of identity and access management (IAM) systems, which verify the identity of users and devices and ensure that they have the necessary permissions to access specific resources. Access is granted on a "need to access" basis, rather than granting broad access to all users and devices within a network.
Network segmentation is also an important aspect of Zero-Trust security. This involves dividing the network into smaller, isolated segments, with access to each segment strictly controlled. This makes it more difficult for attackers to move laterally within the network and gain access to sensitive resources.
Continuous monitoring and detection are also an important part of a Zero-Trust security model. This involves the use of tools and technologies to continuously monitor network activity, identify and alert suspicious activity, and respond to potential threats promptly.
Overall, the Zero-Trust model is designed to protect against the risks associated with insider threats, supply chain attacks, and external threats, and to provide a more secure and controlled environment for accessing and using network resources.
